Subject: [CodeGen] Update a test-case affected by folding IntToPtr/PtrToInt into Loads
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=7e22c8e9b6b4ac7225fe1740cc6fe5221c27533d;p=clang

[CodeGen] Update a test-case affected by folding IntToPtr/PtrToInt into Loads

Folding IntToPtr or PtrToInt into Loads, due to r238452,
perturbs the mips-varargs test-case.

Patch by Philip Pfaffe!

Differential Revision: http://reviews.llvm.org/D9153

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@238455 91177308-0d34-0410-b5e6-96231b3b80d8
